Hi Marcelle,

Which version of RHEL are you using ?

Have you gone through the documentation present in
http://www.redhat.com/docs/manuals/csgfs/
-> This talks about configuring and managing the Red Hat Cluster

Murali

Marcelle,

Could you please paste the cluster.conf file from both the nodes. Also, /var/log/messages (attach it if possible).

Also, what is the RHEL version you using

cat /etc/issue

cat /etc/redhat-release

redhat release 5.3
Red Hat Enterprise Linux Server release 5.3 (Tikanga)

And, attached is /var/log/messages file.

as a point of reference, i'm using two vmware-based nodes with redhat rel 5.3

Marcelle,

In the /var/log/messages I do see the below messages of some concern.

Jun 9 22:24:16 usplsvulx181 ccsd[7503]: Unable to parse /etc/cluster/cluster.conf
Jun 9 22:24:16 usplsvulx181 ccsd[7503]: Searching cluster for valid copy.

Jun 9 22:24:17 usplsvulx181 ccsd[7503]: Error while processing connect: No data available

Also, in case of VMWare the fence configuration is different when compared to two standalone servers. I suggest you to use the system-config-cluster utility to configure the cluster. In case you are using DRAC as a fence device then there please refer the link below:

Also, the document link below gives a complete insight on the Red Hat Cluster configuration
